Про вакансію
UnioTech is a contract engineering company delivering hardware and embedded systems for clients across Europe. We are looking for a Hardware Development Engineer whose primary focus is the design of PCBs and hardware for a wide range of sensor systems — microcontroller- and single-board-computer-based platforms integrating diverse sensors and low-power wireless communication.
Responsibilities:
Sensor system hardware (primary focus)
* Design, develop, and test hardware for sensor systems built around microcontrollers (MCU + sensors) and single-board computers (SBC + sensors).
* Translate system requirements into modular and scalable schematics, PCB layouts, and Bill-of-Material (BoM) selection.
* Design mixed-signal PCBs interfacing to a broad range of sensors, including analog front-ends and digital buses (I2C, SPI, UART, 1-Wire, CAN, RS-485).
* Specify signal-conditioning and data-acquisition chains: amplification, filtering, ADC/DAC selection, voltage references, and noise management.
* Integrate low-power radio communication into sensor nodes — typical transmit power up to ~10 W, operating frequencies up to 5 GHz (e.g., sub-GHz ISM, BLE / 2.4 GHz, Wi-Fi, LoRa). This includes RF front-end, impedance matching, and antenna integration and placement.
* Design power-supply and power-management sub-systems for sensor nodes (LDOs, switching regulators, battery / charge management, low-power and sleep-mode design).
* Ensure signal integrity, EMC/EMI robustness, sound grounding, and predictable thermal behavior across the layout.
* Perform prototype bring-up, hardware debugging, testing, and laboratory validation across the specified environmental operating range (e.g., −20 °C to +70 °C).
Required Qualifications & Hard Skills
* 3+ years of professional hardware/PCB design experience: schematic capture and multi-layer PCB layout for mixed-signal systems.
* Hands-on experience designing MCU-based and SBC-based hardware and interfacing it to sensors over analog and digital interfaces.
* Experience integrating low-power RF/wireless links (up to 5 GHz, up to ~10 W): RF-aware layout, controlled impedance (50 Ω), matching networks, and antenna integration.
* Strong grasp of mixed-signal PCB layout: minimizing noise coupling, grounding strategy, power distribution, and EMC/EMI mitigation.
* Experience bringing up and debugging prototype hardware with standard lab equipment (oscilloscope, multimeter, spectrum analyzer, VNA, etc.).
* Familiarity with EMC and electrical-safety considerations and pre-compliance testing.
* Proficiency with a professional EDA toolchain (e.g., Altium Designer, KiCad, or equivalent).
* Working proficiency in English (client-facing role).
We offer:
* Opportunity to work in an office in Khmelnitsky or ability to work remotely (only in Ukraine);
* Competitive remuneration;
* Constant professional growth and development;
* Provision of equipment as needed;
* A dynamic and supportive work environment, with access to cutting-edge tools and resources;
* The ability to work with the latest modern tools and technologies on different projects;
* 8-hour working day with flexible schedule;
* The company pays taxes, provides accounting and legal support;
* Opportunity to attend courses (English lessons or other related to professional activities)
